My wife recently purchased a 92 525i that needs a little work. One of the problems I'm working on is a vibration at about 65MPH. Lots of threads on this subject.

Thanks to this forum I found that my thrust bushings were bad... so I purchased replacement bushings and the tool to get the old ones out. What a PITA.... and... it turns out my ball joints were bad, too... so I had to buy and install new thrust arms. Sure wish I would of read that thread first (replace the whole arm rather than just the bushings).

The vibration is still present.

I ordered new lower control arms and hopefully will get to them this coming weekend.

Question: Is it possible for a machine shop to replace the ball joints on the control/thrust arms? Can I buy just the ball joint part and have them press the old out and put the new in....??? Where?

Every place I look the whole arm with the BJ is the only option.

Rather than buy another set next year, I'd like to get the old ones refurbished to have as spares.
